Description

Technical Field

[0001] This utility model relates to the field of container ventilation equipment technology, and in particular to a container ventilation device with stable power supply. Background Technology

[0002] With the rise of modular buildings and temporary commercial facilities, the use of converted shipping containers for living spaces, cafes, restaurants, and other applications is becoming increasingly widespread. These applications typically require windows in the side walls or top of the container and the installation of ventilation systems to ensure internal air circulation and environmental comfort. To simplify installation, reduce conversion costs, and achieve green energy efficiency, a large number of solar-powered ventilation systems have emerged in the current technology. These systems typically include solar panels, a controller connected to the solar panels, and a motor and fan driven by the controller. The system operates well under sufficient sunlight.

[0003] However, the power supply for such existing technologies relies entirely on solar energy. On cloudy days, rainy days, or at night when sunlight is insufficient, the output current of the solar panels drops sharply, causing a decrease in the power of the drive motor, significantly reducing ventilation effectiveness or even causing it to stop working altogether. This severely impacts the normal use of indoor environments that depend on stable ventilation, resulting in a poor user experience. Utility Model Content

The detection module is disposed in the power supply circuit between the first controller and the motor and is used to detect the output current value of the first electrical energy in real time. The control module is signal-connected to the detection module, the first controller, and the second power supply component, respectively. The control module controls the second power supply component to start or increase its output to cooperate with or replace the first power supply component in supplying power to the motor, thereby maintaining a stable input power of the motor.

Moreover, by using a detection module to monitor the current value in real time, and having the control module automatically control the start-up or output increase of the second power supply component based on the detection results, intelligent management of the ventilation device's power supply is achieved, eliminating the need for manual intervention and improving the convenience and reliability of use.

[0023] Reference Figure 1 , Figure 2 and Figure 3This utility model proposes a stable power supply ventilation device for containers, including a ventilation body 100, a first power supply component, a second power supply component, a detection module, and a control module 400. The ventilation body 100 is the core component for achieving the ventilation function of the entire device. It includes a housing 110, a motor 120 housed within the housing 110, and a fan 130 driven by the motor 120. The motor 120 serves as the power source, driving the fan 130 to rotate, thereby generating airflow and achieving air circulation inside the container. The first power supply component uses solar power and includes a solar panel 200 and a first controller 210 electrically connected to the solar panel 200. The solar panel 200 is responsible for converting solar energy into electrical energy, and the first controller 210 regulates and manages the converted electrical energy to stably power the motor 120. The first controller 210 is connected to the motor 120, delivering the converted first electrical energy to the motor 120 to drive its operation. The second power supply component is electrically connected to the motor 120 and its function is to provide a second electrical energy source. When the first power supply component cannot provide a stable and sufficient amount of power, the second power supply component can work in conjunction with or replace the first power supply component to supply power to the motor 120, ensuring the normal operation of the motor 120. The detection module is located in the power supply circuit between the first controller 210 and the motor 120. Its main function is to detect the output current value of the first power supply in real time. By accurately detecting the current value, the power supply status of the first power supply component can be understood in a timely manner, providing a basis for subsequent control decisions. The control module 400 is connected to the detection module, the first controller 210, and the second power supply component. It controls the second power supply component based on the first power supply output current value fed back by the detection module. When the detected first power supply output current value is lower than a preset value, it indicates that the first power supply component cannot provide sufficient power. At this time, the control module 400 controls the second power supply component to start or increase its output to work in conjunction with or replace the first power supply component to supply power to the motor 120, thus maintaining a stable input power for the motor 120.

[0024] It should be noted that under normal lighting conditions, the solar panel 200 converts solar energy into electrical energy. After the first controller 210 regulates and manages the electrical energy, a portion of the electrical energy directly powers the motor 120, driving the fan 130 to rotate and achieve the ventilation function. The detection module monitors the current value in the power supply circuit between the first controller 210 and the motor 120 in real time and feeds the data back to the control module 400. When encountering insufficient lighting conditions such as cloudy days or nights, the electrical energy converted by the solar panel 200 decreases, and the output current value of the first electrical energy drops. When the detection module detects that the current value is lower than the preset value, the control module 400 immediately issues a command to start the battery to power the motor 120. The second electrical energy in the battery is delivered to the motor 120 through the circuit, ensuring that the motor 120 can continuously obtain a stable power supply, maintaining the normal speed of the fan 130, thereby ensuring the stable operation of the ventilation device.

[0025] In other embodiments, the second power supply component is a mains power supply module. When it gets dark or there is a prolonged cloudy day, the solar panel 200 cannot provide enough power. After the detection module detects that the first power output current value is lower than a preset value, the control module 400 reacts quickly and the second power supply component is activated. The mains power supply module connects to the mains power supply and converts the mains power into electrical energy suitable for the motor 120, thus powering the motor 120. At this time, the mains power supply module and the first power supply component work together to provide stable power to the motor 120, ensuring that the ventilation device can operate normally in various environments.

[0026] Understandably, by setting up a second power supply component that works in conjunction with the first, when the first power supply component cannot provide stable power due to insufficient sunlight, the second power supply component can promptly start or increase its output, providing stable power to the motor 120. This effectively solves the problem of power reduction in existing solar-powered ventilation devices on cloudy days or at night, ensuring stable operation of the ventilation device in any environment. Furthermore, different types of second power supply components, such as batteries or mains power modules, can be selected according to actual needs, adapting to different usage scenarios and environmental conditions. Whether it's a container dwelling in the wild or a container coffee shop or restaurant in the city, its ventilation needs can be met. By using a detection module to monitor the current value in real time, and the control module 400 to automatically control the start-up or output increase of the second power supply component based on the detection results, intelligent management of the ventilation device's power supply is achieved, eliminating the need for manual intervention and improving ease of use and reliability.

[0027] Reference Figure 1 and Figure 2In this stable power supply container ventilation device, the second power supply component consists of a solar panel 300 and a battery. The solar panel 300 is installed in a suitable location to receive sunlight and is electrically connected to the battery via wires. When sunlight is sufficient, the solar panel 300 converts solar energy into electrical energy and directly supplies it to the battery for storage. The control module 400 is electrically connected to the battery via wires and monitors the battery's status in real time. When the detection module detects that the first power output current value of the first power supply component is lower than a preset value, the control module 400 sends an on signal to the battery, and the battery begins to supply power to the motor 120, supplying the stored second electrical energy to the motor 120 to maintain the stable operation of the motor 120; when the first power supply component returns to normal power supply and meets the needs of the motor 120, the control module 400 sends a off signal to the battery, and the battery stops supplying power. By using the solar panel 300 to convert excess solar energy into electrical energy and store it in the battery, it can replenish the power supply when the first power supply component is insufficient, improving energy utilization and reducing energy waste.

[0028] Furthermore, in addition to the solar panel 300 and the battery, the second power supply component also includes a second controller 320. The second controller 320 is connected to the control module 400 and the motor 120 via wires. During normal operation, the detection module monitors the first power output current value of the first power supply component in real time. When the current value is lower than a preset value, the control module 400 sends an on signal to the second controller 320. Upon receiving the signal, the second controller 320 controls the battery to start supplying power to the motor 120 and precisely controls the amount of electrical energy output to the motor 120 according to the adjustment signal sent by the control module 400. When the first power supply component returns to normal power supply, the control module 400 sends a off signal to the second controller 320, and the second controller 320 stops the battery from supplying power to the motor 120. The second controller 320 allows the control module 400 to more accurately control the on / off state and magnitude of the second power supply component's output, providing appropriate electrical energy according to the actual needs of the motor 120, avoiding oversupply or undersupply of electrical energy, and improving energy utilization efficiency.

[0029] Reference Figure 2The second power supply component is equipped with a mounting frame 310, which consists of a fixing plate 311 and a support frame 312. The fixing plate 311 is fixedly connected to a suitable position on the top of the container using bolts or other fasteners. The support frame 312 is set at a certain angle to the fixing plate 311, and the solar panel 300 is connected to the support frame 312 by bolts or clips, so that the solar panel 300 is arranged at an angle on the mounting frame 310. This inclined arrangement is beneficial for the solar panel 300 to better receive sunlight and improve the solar energy conversion efficiency. The inclined arrangement of the solar panel 300 can maximize the reception of sunlight according to the angle and time of sunlight in different regions, increase the amount of solar energy collected, and thus increase the power reserve of the second power supply component. The design of the mounting frame 310 ensures that the solar panel 300 can be firmly installed on the top of the container, reducing the shaking or damage of the solar panel 300 caused by external factors such as wind and vibration, and ensuring the normal operation of the second power supply component.

[0030] Reference Figure 2 and Figure 3 The ventilation unit 100 has a housing 110 connected to a square liner 140, which has an installation opening 141 for mounting the housing 110. During installation, the liner 140 is fixed to the side wall of the container using fasteners, and its position is adjusted so that both sides are flush with the ribs on the container. This flushing method increases the contact area between the liner 140 and the container side wall, improving the stability of the ventilation unit 100 during installation. The flushing design between the liner 140 and the container ribs allows the ventilation unit 100 to be better secured to the container side wall during installation, reducing vibration and noise during operation and extending the service life of the ventilation device.

[0031] Furthermore, the liner 140 has multiple mounting holes 142 evenly distributed circumferentially. When installing the ventilation unit 100, appropriate fasteners are selected according to the preset hole positions on the container sidewall, passing through the mounting holes 142 to firmly fix the liner 140 to the container. The arrangement of the multiple mounting holes 142 can be flexibly adjusted according to the actual installation situation to ensure the firmness and stability of the liner 140 installation. The evenly distributed mounting holes 142 enable the fasteners to bear force evenly, enhancing the connection strength between the liner 140 and the container, and ensuring the stability of the ventilation unit 100 during operation.

[0032] Reference Figure 1 , Figure 2 and Figure 3It should be noted that the solar panel 200 is installed on the outer surface of the housing 110 by means of adhesive or bolts. A mesh 150 is installed between the solar panel 200 and the fan 130, and the mesh 150 is fixed to the housing 110 by clips or bolts, serving to protect the fan 130 and prevent foreign objects from entering. A ventilation grille 111 is provided at the bottom of the housing 110. The ventilation grille 111 consists of multiple parallel strip structures, allowing airflow to enter and exit the ventilation body 100, thus achieving air circulation inside the container. The design of placing the solar panel 200 on the outer surface of the housing 110 makes full use of the external space of the ventilation device, without occupying internal container space, while also facilitating the solar panel 200's reception of sunlight. The mesh 150 effectively prevents foreign objects from entering the fan 130 area, protecting the normal operation of the fan 130 and extending its service life; the design of the ventilation grille 111 ensures smooth airflow and improves ventilation efficiency.

[0033] Reference Figure 3 The housing 110 is designed as a trapezoidal structure with its width gradually increasing from top to bottom. The solar panels 200 are arranged at an angle on the outermost side of the housing 110 and are fixed to the housing 110 by bolts or adhesive. This trapezoidal structure of the housing 110 not only has a unique appearance but also better adapts to ventilation needs. The angled arrangement of the solar panels 200 optimizes solar energy reception based on the angle of sunlight. The trapezoidal structure of the housing 110 allows for smoother airflow through the ventilation body 100, reducing airflow resistance and improving ventilation efficiency. The angled arrangement of the solar panels 200 maximizes sunlight reception based on the sunlight characteristics of different times and regions, improving solar energy conversion efficiency and providing more abundant power for the ventilation device.

[0034] Reference Figure 1 A sensing module 500 is added to the ventilation system. This module includes temperature, humidity, and carbon dioxide sensors. These sensors are installed in appropriate locations inside the container to acquire real-time data on temperature, humidity, and carbon dioxide levels, transmitting the data to the control module 400 via wires. The control module 400 analyzes and processes the acquired data. When it detects that environmental parameters inside the container exceed preset ranges, it automatically adjusts the input power of the motor 120 to improve the environmental quality inside the container. The sensing module 500 can monitor environmental parameters inside the container in real time and automatically adjust the operation of the ventilation system based on parameter changes, achieving intelligent environmental regulation and providing a more comfortable environment for the personnel inside the container.

[0035] In some embodiments, the ventilation device further includes a user interaction module 600, which takes the form of a display screen and operation buttons. The display screen is signal-connected to the control module 400 and is used to display data such as temperature, humidity, and carbon dioxide content acquired by the sensor module 500. The operation buttons are also signal-connected to the control module 400, allowing the user to send signals to the control module 400 to manually control the input power and on / off state of the motor 120. For example, the user can adjust the ventilation intensity or turn off the ventilation device according to their needs. The user interaction module 600 provides an intuitive operating interface, allowing users to easily view environmental data inside the container and manually control the operation of the ventilation device according to actual needs, thus improving the user experience.

[0036] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
